Title: Discharge lamp lighting device
Inventor: HAYASHI NOBUHIRO
IPC: H05B41/282
Filed: 1993-03-15
Abstract: PURPOSE:To allow the same inverter circuit to efficiently light discharge lamps different in rating by connecting a plurality of discharge lamps in series, making a total of lamp voltage constant, and thereby letting lamp current be of a value as specified by each lamp. CONSTITUTION:When two discharge lamps of 25W each are connected in series by a series lighting circuit 3, the lamp voltage of each discharge lamp is 70V, voltage at both the ends of the circuit 3 is 140V, and power consumption becomes 50W. And when three discharge lamps of 15W each are connected in series, the voltage of each lamp is 45V, therefore, voltage at both the ends of the circuit 3 becomes 135V, and the power consumption will be 45W. Thus, lamp voltage is roughly identical to power consumption in either case as mentioned above. Therefore, if lamp current flowing each discharge lamp is regulated to specified current by each lamp by a lamp current matching means 2, the supply capacity of the inverter circuit 1 can be efficiently consumed by each discharge lamp.

Title: Power generating apparatus
Inventor: HOKOTANI KATSUMI
IPC: F01K25/10
Filed: 1979-05-01
Abstract: PURPOSE: To improve the available temperature efficiency of a power generating apparatus, by using as working fluid a fluid mixture which presents temperature  change from the time when vaporization or condensation under contant pressure is  started to the time when it is terminated, making the working fluid flow in a condenser in a direction opposite to that of a fluid to be heat exchanged, and thereby  enlarging the available temperature range.  
     CONSTITUTION: As working fluid, there is used a fluid which is obtained by mixing at least two kinds of fluid at a proper ratio and presents temperature change in a while from the time when vaporization or condensation under constant pressure is started to the time when it is terminated. For instance, there is used a fluid obtained by mixing Freon coolant R22 and R114 at the volume ratio of 0.95W0.05 in the state of liquid. Here, at least in condenser 2 out of condenser 2 and evaporator 4, the fluid mixture is made to flow in a direction opposite to that of a fluid to be heat exchanged. With such an arrangement, it is enabled to utilize twice the quantity of heat, as compared with that utilized in conventional arrangements, by using a heat source through about 20 degrees 100°→80°C, which results in producing about 1.6 times as much power. Therefore, heat source can be utilized in a wide range, which is effective in saving natural resources.

Abstract: PURPOSE: To reduce the through current of a CMOS logic circuit. CONSTITUTION: This circuit includes an output wire 217 from a pMOS 211 to a load-side CMOS gate 202 between the drive-side pMOS 211 and drive-side nMOS 212 of a drive-side CMOS gate 201 and an output wire 218 from the end to the end of the gate electrode of the pMOS 221 or nMOS 222 of the load-side CMOS gate 211 and from a load-side CMOS gate 211 to an nMOS in series. Therefore, a delay circuit is considered to be interposed between the drive-side pMOS and drive-side nMOS, and a difference in output waveform is generated between the output terminal of the nMOS and pMOS output terminal to advance transition from 'ON' to 'OFF' of the pMOS or nMOS during this delay, so the through current is reduced.  Further, the load-side CMOS gate has a difference between a pMOS gate input and an nMOS gate input, so both the pMOS and nMOS have delay in the direction wherein the time of 'ON' decreases, so the through current is further reduced.
